Tuesday, Iris Harris brought her daughter and friends down to lay down flowers and balloons at a makeshift memorial for Charles Walker.

Friends say the 15-year-old, who went by CJ or Chuck, was killed while delivering Timberland shoes to his girlfriend. "Somebody came up and said 'give me them shoes' and he was like, 'nah, nah' and they pulled a gun," said one friend. The person then shot him and ran, according to the friend.
